Description	The two large (width is indeterminate) dry laid and dressed ashlars seem to provide a deep foundation for the overlying structures. The curious construction of both Loci 29 and 30 create a space in-between of 0.80 east west-by-0.32 m north south gap that is not a channel. It appears the large ashlars were laid as a platform for the construction of the further architectural elements.
